Abstract
The combined benefits of decision feedback equalization and error correction coding are realized in a communications system by the use of a plurality of coders and decoders respectively disposed in the transmitter and receiver. The plurality of encoders and decoders is used to interleave the data symbols so that each coder and decoder is operative upon every Mth symbol, where M is the number of coders or decoders. By a judicious choice of M, both the probability of noise impairing the recovery of successive symbols and the error propagation effects inherent in decision feedback equalizers are reduced.
